Ok, the entire serial killer thing aside, Alastor would be an amazing Lavender Husband.
Lavender Marriages were marriages of convenience between a man and a woman to conceal the socially stigmatized sexual orientation of one or both partners.
Just, think about it. As a woman in the early 20th century in the United States you'd have close to zero freedom. Barely with a right to vote, women still couldn't live independently.
Now, while married to Alastor you'd have guaranteed freedom from any form of unwanted martial sexual activities. No unwanted touches either!
Alastor holds deep admiration, and respect for women (due to his mother) and has always preferred feminine company. This guy would actually be interested in what you have to say! Your opinions, beliefs, dreams - all of those are valid and he's unironically listening to them.
Thanks to his mother, he'd never make you beg for money in times when you can't even open your own bank account. He'd also support you in your own employment. If the workplace requires your husband's permission he'd just sign it and move on with his day.
Don't even get me started on entertainment with this guy! He plays the piano, he's a good dancer, he's charming and charismatic enough to work as a radio host. You'd never be bored with him! Even if you're more of an indoors, bookish person he would just leave you to it. He's completely capable of having his separate life and you never have to worry about him cheating on you.
Bedsides, if anyone wrongs you you do know they won't go unpunished...
While he might not give you complete freedom when it comes to decorating your house, you can live sound and be sure that he'd never hit you no matter how drunk he'd be.
Like, considering times, especially if you are a PoC - he's a jackpot!
